temperature of the automatic
transmission f luid. The indicator
should come on f or a f ew seconds
when you turn the ignition switch to
ON (II). If it comes on while driving,
it indicates the transmission f luid
temperature is too high. Pull to the

f lashes while driving (in any shif t
position), it indicates a possible
problem in the transmission.If the malf unction indicator lamp
come on along with the ‘‘D ’’

automatic transmission control
system. Avoid rapid acceleration and

This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot of f the
accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page .
To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch. Press the brake
pedal to shift from Park to Reverse.
To shif t f rom Reverse to Neutral,
come to a complete stop and then
shif t.
Your vehicle has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 7 9 mph (12 14
km/h).
If you cannot shif t to Reverse when
the vehicle is stopped, press the
brake pedal and slowly shift to
Neutral, and then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s
battery is disconnected or goes dead,
you cannot shif t to Reverse. (Ref er
to Shif t Lock Release on page ). Use Neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from Neutral to
another gear.
Use this position f or
normal driving. The transmission
automatically selects a suitable gear
f or your speed and acceleration. You
may notice the transmission shif ting
up at higher speeds when the engine
is cold. This helps the engine warm
up f aster.

µµ µThese positions
are similar to D , except when you
select the D position, only the f irst
f our gears are selected. When you
select D , only the f irst three gears
are selected. D can also keep the
transmission f rom cycling between
f ourth and f if th gears in stop-and-go
driving, and D can keep the
transmission f rom cycling between
third and f ourth gears. This position locks
thetransmissioninsecondgear.It
does not downshif t to f irst gear
when you come to a stop.
Use Second gear: For more power when climbing.
To increase engine braking when
going down steep hills.
For starting out on a slippery
surf ace or in deep snow.
When driving downhill with a
trailer. With the lever in this
position, the transmission locks in
First gear.
If you shif t into First position when
the vehicle speed is above 31 mph
(50 km/h), the transmission shif ts
into Second gear f irst to avoid
sudden engine braking.
If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone.
Use D to provide engine braking
when going down a steep hill. D
gives you more power and increased
engine braking.

The Variable Torque Management
4WD System (VTM-4) automatically
transf ers varying amounts of engine
torque to the rear wheels under
lower traction conditions.
If more traction is needed when your
MDX is stuck, or is likely to become
stuck, you can use the VTM-4 Lock
button to increase torque to the rear
wheels.The vehicle must be stopped with
the engine running.
Move the shift lever to First (1),
Second (2), or Reverse (R) gear.
Press the VTM-4 Lock button.
The light in the button will come
on.
To get unstuck, apply light pressure
to the accelerator pedal. Do not spin
the f ront tires f or more than a f ew
seconds. Because of the amount of
torque applied to the rear tires, they
should not spin. This is normal. If
you are not able to move the vehicle,
stop and reverse direction. do
one of the f ollowing: Press the VTM-4 Lock button.
Move the shift lever to D , D or
D.
Turn the ignition switch to LOCK
(0).
The VTM-4 Lock will temporarily
disengage when the vehicle speed
exceeds 18 mph (30 km/h). It will
automatically engage again as the
speed slows below 18 mph (30
km/h). The button light will remain
on.

NOTICE: NOTICE:
Do not use the VTM-4 Lock
button on dry, paved roads. Driving on
dry, paved roads with VT M-4 Lock ON
may damage the rear dif f erential when
making a turn. Strange noise and
vibration can also result. Do not continuously spin the
f ront tires of your MDX. Continuously
spinning the f ront tires can cause
transmission or rear dif f erential
damage.

When driving with a f ix-sided (e.g.
camper, utility) trailer, do not
exceed 55 mph (88 km/h). At
higher speeds, the trailer may
sway or affect vehicle handling.
Whenbeingpassedbyatruckor
large vehicle, cross-winds and air
turbulence can disrupt your
steering and cause your trailer to
sway. Keep a constant speed, steer
straight ahead, and do not try to
make quick steering or braking
corrections.
Do not park on an incline unless it
is unavoidable. If you must, turn
the vehicle’s wheels toward the
curb on a downhill or away f rom
the curb on an uphill. Af ter
parking, place wheel chocks at
each trailer tire on the downhill
side.Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; then turn the wheel to the lef t
to get the trailer to move to the lef t,
andturnthewheelrighttomovethe
trailer to the right.
If the vehicle’s wheels slip when
retrieving a boat f rom the water,
shif t to f irst gear, and turn on VTM-4
Lock (see page ). Disengage
VTM-4 Lock as soon as the boat is
out of the water to prevent damage
to the VTM-4 system.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, reduce speed
and, if necessary, pull to the side of
the road and let the engine cool.
If the transmission shif ts f requently
while going up a hill, shif t down one
gear.
If youmuststopwhenfacinguphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
this could cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shif t down to D . Do
not ‘‘ride’’ the brakes.
